1. Choose a pressure cooker with non-stick liner. Choose sweet potatoes that have been left for a while and are a little dry.

2, this sweet potato has less water and good sweetness, about a catty. The head should be consistent as far as possible, not too big, and the big sweet potato can be cut.

3. Wash the sweet potato, dry it, tie some small holes in the sweet potato, tie them evenly, about one centimeter deep, tie 3 holes around the sweet potato, and tie about 5 layers.

4. Put the processed sweet potato into the rice cooker. Choose rice to cook for 20-30 minutes, heat it for a long time, then dry it, and the taste is closer to fire roasting.

5. Wait a few minutes after cooking, open the lid and let the sweet potato dry for a while.
